Formula used

If PM and hour is not 12, add 12 to the hour. If AM and hour is 12, use 00. Military time = two-digit 24-hour hour followed by two-digit minutes. Decimal hour = 24-hour hour + minutes ÷ 60. Optional end time adds duration minutes modulo 24 hours.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Best for shift notes, transport and travel plans, classroom time worksheets, medical appointment cards, event schedules and any record where 2:30 PM should be written unambiguously as 1430.

  • The calculator uses ordinary civil 24-hour clock notation, displayed as military-style HHMM without a colon and as 24-hour time with a colon.
  • 12:00 AM is midnight and becomes 0000; 12:00 PM is noon and becomes 1200.
  • The AM/PM selector is stored deterministically: AM is 0 and PM is 1 behind the interface.
  • Optional duration is added after conversion and wraps after 24 hours for next-day planning notes.
  • This is a time-format conversion, not a time-zone, daylight-saving, payroll-law or official roster approval tool.

Master’s Tip

How to use the result well

Master’s Tip: print both the original 12-hour time and the military-time result when handing a note to someone else. Most mistakes happen around noon, midnight or a missing AM/PM mark, not in the minute arithmetic.

Method

If PM and hour is not 12, add 12 to the hour. If AM and hour is 12, use 00. Military time = two-digit 24-hour hour followed by two-digit minutes. Decimal hour = 24-hour hour + minutes ÷ 60. Optional end time adds duration minutes modulo 24 hours.

  1. For 2:30 PM, PM is selected and the hour is not 12, so 12 is added: 2 + 12 = 14. Military time is 1430, 24-hour time is 14:30, and the decimal-hour cross-check is 14 + 30 ÷ 60 = 14.5.

Assumptions

  • The calculator uses ordinary civil 24-hour clock notation, displayed as military-style HHMM without a colon and as 24-hour time with a colon.
  • 12:00 AM is midnight and becomes 0000; 12:00 PM is noon and becomes 1200.
  • The AM/PM selector is stored deterministically: AM is 0 and PM is 1 behind the interface.
  • Optional duration is added after conversion and wraps after 24 hours for next-day planning notes.
